0.125×0.32-0.25×0.16=0.125×0.32-0.125×2×0.16=0.125×0.32-0.125×(2×0.16)=0.125×0.32-0.125×0.32=0
67*0.25+2.5*3.75-4.5*0.25=67×0.25+0.25×37.5-4.5×0.25＝（67+37.5-4.5）×0.25＝100×0.25＝25
(2.5*0.4)*(0.8*12.5)=1*10=10
75－（6.8＋0.32×0.25×12.5）=75-（6.8+0.4*0.25*0.8*12.5）=75-（6.8+0.1*10）=75-（6.8+1）=75-7.8=67.2
=75-（6.8+0.4*0.8*0.25*12.5）=75-[6.8+(0.4*0.25)*(0.8*12.5)]=75-(6.8+0.1*10)=75-7.8=67.2
=4x0.25x1.25x0.08=1x0.01=0.01再问：你确定是对的吗
0.32*12.5*2.5=0.4**0.8*12.5*2.5=0.4*2.5*0.8*12.5=1*10=10
=（12.5×0.8）×（2.5×0.4）=10×1=1088×125=11×（8×125）=11×1000=11000
36×2.5=9x4x2.5=9x10=90（12.5+0.25）×8=12.5x8+0.25x4x2=100+1x2=1020.125×7.2=0.125x8x0.9=1x0.9=0.9401×0.
0.32×0.25×0.125×100=（0.4*0.25）*（0.8*12.5）=0.1*10=1数学辅导团祝你学习进步,不理解请追问,理解请及时采纳!(*^__^*)
2.5×0.32×1.25=（1.25×0.8）×（2.5×0.4）=1×1=1
(0.75*6.4*93)/(2.5*0.62*0.32)=(0.75/2.5)*(6.4/0.32)*(93/0.62)=3/10*20*150=900祝开心
0.32除以0.25=0.32除以4分之1=0.32乘以4=1.28
=-0.75-2.5+0.25=-0.75+0.25-2.5=-0.5-2.5=-3这个是最详细的解法
2.5×1.25×0.32=2.5×1.25×0.4×0.8=(2.5×0.4)×(1.25×0.8)=1×1=1
1.25x2.4=1.25x2+1.25x0.4=2.5+0.5=31.25x0.32x2.5=(1.25x0.8)x(0.4x2.5)=1x1=11.25x2.5x64=1.25x8x(2.5x8)
0.25*0.32*1250=0.25*0.4*0.8*1250=0.1*1000=100
125×0.32×2.5，=（125×0.8）×（0.4×2.5），=100×1，=100．
1/2.5-0.25(1-1)=1/2.5=0.4
0.46*2.5+6.4*0.25-0.25=4.6*0.25+6.4*0.25-0.25=(4.6+6.4-1)*0.25=10*0.25=2.5
